七十年代发展起来的一类昆虫几丁质合成酶抑制剂,是一类干扰昆虫表皮几丁质合成的苯基苯酰基脲类衍生物。因为只对幼虫具有阻止蜕皮的生物活性,所以是一类新的干扰几丁质沉积的杀幼虫剂。1970年荷兰菲利普—道费尔公司从除草剂的筛选中发现,由美国汤姆森—哈迈德公司对该药进行了发展,并对作用机理和作为害虫控制剂进行了广泛的研究。这类新型的害虫防治剂,它们的杀虫机理不同于有机磷和有机氯杀虫剂。它是抑制几丁质合成酶和干扰几丁质在 A kind of insect chitin synthase inhibitor developed in the seventies, is a class of phenyl benzoylurea derivatives that interfere with the synthesis of insect epidermis chitin. It is a new class of larvicidal agents that interfere with chitin deposition because it has only the biological activity of larvae to deter molting. In 1970, the Phillip-Downer company in the Netherlands discovered from a screening of herbicides that the drug was developed by the Thomson-Ahem Company in the United States and extensively studied its mechanism of action and its role as a pest control agent. The new pest control agents, their insecticidal mechanism is different from the organic phosphorus and organochlorine pesticides. It inhibits chitin synthase and interferes with chitin in it
